From measurement mode:
1.
Press the Mode key to select
conductivity or TDS measurement
mode.
1. Press the Set up key to enter Set Up
mode.
2. Press the ▲ and ▼ keys to scroll
through subgroups until you view
parameter P6.0.
See figure
3. Press the ENTER key repeatedly
to view the effective cell constant for
each range.
Range Conductivity: TDS:
P6.1 (R1) 0.00-19.99 µS 0.00-9.99 ppm
P6.2 (R2) 0.0-199.9 µS 10.0-99.9 ppm
P6.3 (R3) 0-1999 µS 100-999 ppm
P6.4 (R4) 0.00-19.99 mS 1.00-9.99 ppt
P6.5 (R5) 0.0-199.9 mS 10.0-199.9 ppt
See figure
4. When you have scrolled through all
probe data, you will automatically
return to the subgroup menu. Press
the CAL/MEAS key to return to
measurement mode.
Notes
Cell constants will degrade with time and
usage. You can use this feature to alert you
to when your probe needs cleaning or to
when you need to replace your probe.
P6.0: Viewing conductivity/TDS probe data
Program 3 has five "view only" options that let you check your conductivity/TDS
probe’s parameters for diagnostic purposes. These options show you the effective cell
constant for each range. The cell constant is adjusted according to your calibration.

4. Press the ENTER key repeatedly to
view previous calibration data.

5. When you have scrolled through all
calibration data, you will automatically
return to the subgroup menu. Press the
CAL/MEAS key to return to measure-
ment mode.
Notes
If there is no previous calibration data at a
particular point, the primary display will
show “– – –”.
See figure
P5.0: Viewing previous conductivity/TDS calibration data
This mode lets you recall previous conductivity or TDS calibration data, which lets
you know at which points this meter was previously calibrated. This is a “view only”
mode.
TDS values are proportional to conductivity values. Note that if you calibrate a TDS
value in an equivalent conductivity range, the TDS value will replace the previous
conductivity value, and vice versa.
